The dual-activated circulation valve offers the traditional method of returning circulation of the tool string through use of a drop ball. The valve is capable of operating through internal overpressure within the tubing string.

Conventional dual circulation valves use a burst or rupture disc to return circulation through overpressure. However, the dual-activated circulation valve offers a pressure-differential-activated piston. The piston activation pressure can be predetermined at the surface through shear pins, offering superior flexibility and considerable savings on redress.

As with many other tools in the standard bottomhole assembly tool range, the emphasis is on simplicity, and the dual-activated circulation valve has very few component parts, seals, and thread connections.

When ordering dual-activated circulation valves, please specify size and thread connection.
